to identify Amish enclaves in order to determine which might be likely to become isolated and susceptible to “violent, ideologically based extremism,”
The police are concerned that the Amish might become VICTIMS of ideological extremism. Amish are frequent targets of abuse and sometimes violence. Because they will not defend themselves and because they are isolated and without phones.
I think the old order is on there way out of the area, maybe North Central PA or Indiana.
